Almost Gibbsian Measures on a Cayley Tree

Mathematical Physics 2022-02-01 v3 math.MP Probability

Abstract

We consider the ferromagnetic n.n Ising model on Cayley trees in absence of external fields submitted to a modified majority rule transformation with overlapping cells already known to lead to non-Gibbsian measures. We describe the renormalized measures within the Generalized Gibbs framework and prove that they are Almost Gibbs at any temperature.
